As recently as the early '80s there were -- count 'em -- two pharmacies down the street from my office, in Milwaukie, Oregon, that had soda fountain/lunch counters, right across the street from each other. One was a very friendly Rexall, and I became a semi-regular. Interestingly, the woman behind the counter/proprietor had never heard of a chocolate phosphate before I asked for one: I got a "What the hell's that?" kind of look. When I explained, she mixed one up, and one for herself, tried it, smiled and said "That's not bad." I told her I grew up with them in Chicago. She said: "Figures."
